Standard boot has been in place for a while now. Quite a few problems
have been found and fixed. It seems like a good time to mark the
script-based approach as deprecated and encourage people to use standard
boot.
Update the DISTRO_DEFAULTS Kconfig to encourage people to move to
standard boot, which is able to boot Linux distributions automatically.
Add a short migration guide to make this easier.

Some bootmeths support scanning a partition without a filesystem on it.
Add a flag to support this.
This will allow the ChromiumOS bootmeth to find kernel partition, which

The usage of proftool in docs is incorrect. If proftool is used without
'-o' argument, it will show the usage like following
$ ./sandbox/tools/proftool -m sandbox/System.map -t trace -f funcgraph dump-ftrace >trace.dat
Must provide trace data, System.map file and output file

Add a new 'cedit' command which allows editing configuration using an
expo. The configuration items appear as menus on the display.
This is extremely basic, only supporting menus and not providing any way

The only way to create an expo at present is by calling the functions to
create each object. It is useful to have more data-driven approach, where
the objects can be specified in a suitable file format and created from
that. This makes testing easier as well.
Add support for describing an expo in a devicetree node. This allows more
complex tests to be set up, as well as providing an easier format for
users. It also provides a better basis for the upcoming configuration
editor.

It looks better if menus have a bit of an inset, rather than be drawn hard
up against the background. Also, menu items look better if they have a bit

It is a pain to manually set the fonts of all objects to be consistent.
